log2

Description

Returns the base-2 logarithm of a number. Equivalent to log(2, number).

Syntax

Like many functions in DataPrime, log2 supports two notations, function and method. These interchangeable forms allow flexibility in how you structure expressions.

Function notation

log2(number: number): number

Method notation

(number: number).log2(): number

Arguments

Name	Type	Required	Description
number	number	true	The value whose base-2 logarithm will be computed

Example

Use case: Apply a log base 2 transformation

Compute the log base 2 of a numerical field and store the result in a new field.

Example data

{
    "some_value": 16
}

Example query

Function notation

create log_field from log2(some_value)

Method notation

create log_field from some_value.log2()

Example output

{
    "some_value": 16,
    "log_field": 4
}
